Description

  The present invention relates to a greening member, a greening panel, and a method for manufacturing a greening wall used for, for example, a fence or an outer wall of a building.

  In order to reduce carbon dioxide and alleviate the heat island phenomenon in summer, a method has been developed to cover a wall or an outer wall of a building with a tree planted with moss (see Patent Documents 1 and 2). When a green panel is used on a horizontal surface such as a rooftop of a building, it is difficult for rain water to flow out of the green panel. For this reason, sufficient water | moisture content can be ensured for the growth of moss.

  However, when a greening panel is used for a standing wall such as a fence or a side wall of a building, water due to rain tends to flow down along the standing wall due to gravity. For this reason, it is difficult to ensure sufficient moisture for the moss growth in the greening panel.

  Therefore, Patent Document 3 discloses a greening panel having an outer surface with a sawtooth cross section. The greening panel described in Patent Document 3 includes an upward inclined surface. For this reason, it is difficult for water to flow down during rainfall.

Japanese Patent Laid-Open No. 2004-57132 JP 2004-275039 A JP 2004-49064 A

  However, in the case of the greening panel described in Patent Document 3, since the cross-sectional shape of the outer surface is a saw blade shape, the volume of the design portion is increased. In addition, since the saw blade shape inevitably appears on the outer surface, the degree of freedom in designing and designing the outer surface shape is reduced.

  The greening member, greening panel, and greening wall manufacturing method of the present invention have been completed in view of the above problems. An object of the present invention is to provide a greening member, a greening panel, and a method for manufacturing a greening wall having high water retention, external shape design, and high design flexibility.

  (1) In order to solve the above-mentioned problem, the greening member of the present invention is made of a tie layer on which a moss plant gametophyte is arranged, and a non-woven fabric that is arranged on the back side of the tie layer and contains a modified cross-section fiber. And a water retention layer for supplying moisture to the binding layer. Here, the irregular cross-section fiber means a fiber whose axial cross-sectional shape is other than a perfect circle.

  The greening member of the present invention includes a water retention layer made of nonwoven fabric. The water retention layer contains a modified cross-section fiber. The irregular cross-section fiber has a higher specific surface area per unit mass than the perfect circular cross-section fiber. And since it is a fine shape, there exists the characteristic which is easy to maintain a fine water droplet. This is similar to the hairy structure found in plant stems and leaves. For this reason, water retention is high. Therefore, it is particularly suitable for use on a standing wall (of course, it can also be used on a horizontal wall). Moreover, the greening member of this invention can ensure high water retention irrespective of the cross-sectional shape of an outer surface. Therefore, the outer surface shape design and design freedom are high.

  (2) Preferably, in the configuration of (1) above, the modified cross-section fiber is at least one of a Y-shaped cross-section fiber having a Y-shaped cross section and a heat-split fiber that is split by heat. Good. According to this configuration, high water retention can be easily ensured.

  (3) Preferably, in the configuration of the above (1) or (2), a protective layer that is disposed on the front side of the binding layer and promotes the temporary roots of the moss plant gametophyte to take root in the binding layer. It is better to have a configuration with. According to this configuration, the protective layer covers the moss plant gametophyte. For this reason, in the manufacturing process of a greening member, it can suppress that a moss plant gametophyte receives damage from the outside. Moreover, it can suppress that a moss plant gametophyte falls off from a tie layer by a wind, gravity, etc.

  (4) Preferably, in the configuration of (3) above, the protective layer is preferably water-soluble. According to this configuration, the protective layer is easily dissolved by rain or the like. For this reason, after the temporary root of the moss plant gametophyte has taken root in the binding layer, the protective layer can be easily removed.

  (5) Preferably, in the configuration of (3) above, the protective layer is preferably porous and water-insoluble. Here, the “porous shape” includes a woven fabric shape, a nonwoven fabric shape, a knitted shape, a sponge shape, and a net shape. According to this configuration, the moss plant gametophyte or moss can grow while being entangled with the protective layer. For this reason, it can suppress that a moss plant gametophyte or moss falls off from a greening member.

  (6) Preferably, in the configuration of (3) above, the protective layer is preferably configured to have a porous water-insoluble portion and a water-soluble portion. According to this configuration, the water-soluble part is easily dissolved by rain or the like. For this reason, after the temporary root of the moss plant gametophyte has taken root in the binding layer, the water-soluble part can be easily removed. In addition, the moss plant gametophyte or moss can grow while entangled with the water-insoluble part.

  (7) Preferably, in the configuration of any one of the above (1) to (6), the artificial turf is preferably planted from the front side of the binding layer. According to this configuration, even if the growth of the moss plant gametophyte is slow, or the moss plant gametophyte withered, the moss plant gametophyte should have a beautiful appearance with the artificial grass even if the color of the moss plant gametophyte is poor. Can do. In addition, the moss plant gametophyte can be protected from artificial mischief, wind, and pressure.

  (8) Preferably, in the configuration of any one of the above (1) to (7), it is preferable that the surface is provided with a water retaining groove. According to this configuration, the flow of water can be blocked by providing the groove. For this reason, it becomes possible to suppress the dispersion | variation in the water retention of the whole greening member by the water absorption capability which the water retention layer has, and water retention becomes high.

  (9) Preferably, in any one of the above configurations (1) to (8), a configuration is provided that includes a blocking layer that is disposed on the back side of the water retention layer and prevents the moisture from escaping from the water retention layer. Is good. According to this configuration, it becomes difficult for moisture to escape from the back side of the water retention layer. For this reason, water retention is further increased.

  Moreover, after the greening member of this structure is integrated in the greening panel and the said greening panel and the wall main body are integrated, the permeation of water from the greening member to the wall main body can be suppressed. For this reason, durability of a wall main body is improved.

  (10) Preferably, in the configuration of (9) above, a heat insulating layer made of nonwoven fabric is provided between the water retaining layer and the barrier layer, and the barrier layer is heat-sealed to the back surface of the heat insulating layer. It is better to have a configuration. According to this structure, a water retention layer and a moss plant gametophyte can be protected from the heat | fever at the time of heat-sealing a interruption | blocking layer to a heat insulation layer.

  (10-1) Preferably, in the configuration of the above (10), the heat insulating layer is preferably configured to have a water retention capability that supplements the water retention capability of the water retention layer. The water retention layer secures the water necessary for the growth of the moss plant gametophytes. However, the water retention layer is close to the moss plant gametophytes. For this reason, when the water retention capacity of the water retention layer is excessively increased, the water content becomes excessive, and the moss plant gametophytes may become ill.

  In this regard, according to the present configuration, the heat insulating layer has a water retention capability. For this reason, compared with the case where the water | moisture content required for the growth of a moss plant gametophyte is ensured only with a water retention layer, the amount of water retention can be increased. Therefore, for example, even in a place where there is little rainfall, the moss plant gametophyte is likely to grow without being in a tentative state (dormant state).

  Moreover, the heat insulation layer is spaced apart from the moss plant gametophyte compared to the water retention layer. For this reason, it is difficult for the moss plant gametophytes to reach the heat insulating layer. Therefore, it is difficult for the moss plant gametophytes to be immersed in the moisture of the heat insulating layer. Therefore, moss plant gametophytes are less likely to become ill. On the other hand, when the moisture of the water retaining layer is insufficient, the moisture of the heat insulating layer moves to the water retaining layer. For this reason, the water | moisture content of a water retention layer can be replenished. Thus, the heat insulation layer of this structure has the backup function of a water retention layer.

  (11) Moreover, in order to solve the said subject, the greening panel of this invention is the greening member of said (9) or (10), the base material arrange | positioned on the back side of this greening member, this greening member, and this And an adhesive layer that is disposed between the substrate and detachably holds the greening member with respect to the substrate.

  The greening member of the greening panel of the present invention includes a water retention layer made of nonwoven fabric. The water retention layer contains a modified cross-section fiber. The irregular cross-section fiber has a large specific surface area and high water retention compared to a perfect circular cross-section fiber. For this reason, water retention is high. Moreover, the greening panel of this invention can ensure high water retention irrespective of the cross-sectional shape of an outer surface. Therefore, the outer surface shape design and design freedom are high.

  According to the greening panel of the present invention, the greening member is attached to the base material via the adhesive layer. For this reason, for example, when there is a problem that the moss plant gametophyte witheres due to disease or the like, the greening member can be easily replaced. Therefore, the greening panel of the present invention is excellent in maintainability.

  (12) Moreover, in order to solve the said subject, the manufacturing method of the greening wall of this invention is a manufacturing method of the greening wall provided with the greening panel of said (11), and a wall main body, Comprising: A mold form assembly process for assembling the mold form incorporating the greening panel so that the back surface becomes a part of the mold face, and a wall material having fluidity is injected into the mold form, and the wall material is cured. The greening panel and the wall main body are integrated by disassembling the mold and the molding step of performing the molding of the wall main body and the joining of the base material and the wall main body in parallel. A mold disassembling step for obtaining the greening wall.

  The manufacturing method of the greening wall of this invention has a formwork assembly process, a formation process, and a formwork disassembly process. In the mold assembly process, the green panel is assembled and the mold is assembled. At this time, the back surface of the substrate is made a part of the mold surface (molding surface). In the molding step, a wall material is injected into the mold and the wall material is cured. At this time, the back surface of the substrate is joined to the wall body. In addition, the wall body is molded. In the mold disassembly process, the mold is removed. In this way, a greening wall in which the greening panel and the wall body are integrated is completed.

  According to the manufacturing method of the greening wall of this invention, attachment of the greening panel with respect to a wall main body and shaping | molding of a wall main body can be performed in parallel. For this reason, compared with the case where a greening panel is attached to the wall body as a retrofit, the degree of freedom of the attachment location (for example, a high place) is increased. Moreover, the installation cost can be reduced. In addition, a blocking layer is interposed between the wall material and the water retention layer. For this reason, it can suppress that the content of a wall material enters a water retention layer through a base material.

  (12-1) Preferably, in the configuration of (12) above, the base material is preferably made of cement or calcium silicate. The substrate is porous. For this reason, the wall material penetrates well into the base material in the molding step. Therefore, the bondability between the wall body and the base material is improved.

  (12-2) Preferably, in the configuration of (12) above, the base material is preferably made of a material selected from a resin foam, a fiber reinforced resin, a glass foam and the like. The substrate is preferably lightweight. Moreover, it is preferable that the base material has high strength. If the substrate is made of resin foam or glass foam, the substrate can be reduced in weight. Further, when the base material is made of fiber reinforced resin, the base material can be reduced in weight and strength.

  Hereinafter, embodiments of the greening member, the greening panel, and the manufacturing method of the greening member of the present invention will be described.

<First embodiment>
[Composition of green wall]
First, the structure of the greening wall of this embodiment is demonstrated. In FIG. 1, the perspective view of the greening wall of this embodiment is shown. FIG. 2 shows a partial perspective view of the greening wall. FIG. 3 shows an exploded partial perspective view of the greening wall. FIG. 4 shows a cross-sectional view in the IV-IV direction of FIG. 2 to 4 show a portion of the greening wall 1 corresponding to one greening panel 2.

  As shown in FIGS. 1 to 4, the greening wall 1 includes a panel connector 9, a wall body 7, a shaft foot 50, a separator 51, a regicon (registered trademark, manufactured by Okabe Co., Ltd.) 52, and a clip 53. And a cap nut 54.

(Wall body 7, shaft foot 50, separator 51, regicon 52, clip 53, cap nut 54)
The wall body 7 is made of concrete and has a block shape. A set of the shaft foot 50, the separator 51, the regicon 52, the clip 53, and the cap nut 54 is arranged on the wall body 7 at predetermined intervals.

  The separator 51 is made of steel and has a round bar shape. The separator 51 extends in the front-rear direction. The separator 51 is embedded in the wall body 7. Threaded portions are arranged at both ends of the separator 51 in the front-rear direction (axial direction).

  The regicon 52 is made of resin and has a short-axis cylindrical shape. Concave portions are formed on both front and rear sides of the regicon 52. A screw portion is disposed on the inner peripheral surface of the recess. By screwing the screw portion of the regicon 52 and the screw portion of the separator 51, the regicon 52 is fixed to both ends of the separator 51 in the front-rear direction. The regicon 52 is exposed from the front and rear surfaces of the wall body 7. The rear recess of the rear register 52 is sealed with a filler or a cap.

  The shaft leg 50 passes through the greening panel 2 described later, and is fixed to a front recess of the front register 52. The clip 53 is made of steel and is attached to the shaft foot 50. The clip 53 is interposed between the cap nut 54 and a wire mesh 23 described later.

(Panel connector 9)
The panel coupling body 9 has a rectangular plate shape. The panel connection body 9 is formed by connecting a total of 15 greening panels 2 (5 rows (upper and lower) × 3 columns (left and right)). The greening panel 2 includes a greening member 20, a base material 21, an adhesive layer 22, and a wire mesh 23. The base material 21 is made of cement and has a rectangular plate shape. The base material 21 is laminated on the front surface (surface) of the wall body 7.

  FIG. 5 shows an enlarged view in the frame V of FIG. As shown in FIG. 5, the greening member 20 includes a binding layer 200, a water retention layer 201, a protection layer 202, a large number of artificial turf 203, a blocking layer 205, and a heat insulating layer 206.

  The tie layer 200 is a spunbond nonwoven fabric. In the early stage of moss growth, the moss plant gametophyte 200a is arranged in the adhesive layer 200. As shown in FIG. 3, the moss plant gametophyte 200 a grows by being rooted in the binding layer 200 and covers the front surface of the greening member 20.

  Returning to FIG. 5, the protective layer 202 is made of polyvinyl alcohol (PVA). The protective layer 202 is laminated on the front surface of the binding layer 200. The protective layer 202 has water solubility. For this reason, due to rain or the like, the protective layer 202 dissolves with time, eventually disappears, and does not hinder the growth of the moss plant gametophyte 200a.

  A large number of artificial turf 203 is planted in front of the protective layer 202 in a predetermined pattern. The root of the artificial turf 203 penetrates the protective layer 202, the binding layer 200, and the water retention layer 201, and reaches the heat insulating layer 206 described later.

  The water retention layer 201 is made of a non-woven fabric containing a modified cross-section fiber. The water retention layer 201 is laminated on the rear surface (back surface) of the binding layer 200. The water retaining layer 201 holds moisture necessary for the growth of the moss plant gametophyte 200a.

  The heat insulation layer 206 is made of nonwoven fabric and is laminated on the rear surface of the water retention layer 201. The heat insulating layer 206 protects the water retaining layer 201 and the binding layer 200 (that is, the moss plant gametophyte 200a) from heat generated when a barrier layer 205 described later is laminated on the heat insulating layer 206. The heat insulating layer 206 backs up the water retention capacity of the water retention layer 201.

  The barrier layer 205 is made of polyethylene (PE). The blocking layer 205 is laminated on the rear surface of the heat insulating layer 206. The blocking layer 205 suppresses leakage of alkali components of the base material 21 and the wall body 7 to the heat insulating layer 206. In addition, the blocking layer 205 suppresses the moisture of the water retention layer 201 from leaking to the base material 21 and the wall body 7.

  The adhesive layer 22 is a double-sided tape. The adhesive layer 22 is interposed between the rear surface of the blocking layer 205 and the front surface of the base material 21. The greening member 20 is detachably attached to the base material 21 by the adhesive layer 22.

  The metal mesh 23 covers the front surface of the protective layer 202. As shown in FIG. 3, the wire mesh 23 is pressed against the front surface of the protective layer 202 by a clip 53.

[Manufacturing method of greening panel]
Next, a method for manufacturing the greening panel 2 will be described. The manufacturing method of the greening panel 2 has a greening member manufacturing process and a greening member adhesion process.

(Greening member manufacturing process)
The greening member manufacturing process includes a front side lamination process, a back side lamination process, and a front and back layer combination process. In FIG. 6, the schematic diagram of the 1st step of a front side lamination process is shown. In FIG. 7, the schematic diagram of the 2nd step of the same process is shown. FIG. 8 shows a schematic diagram of the third stage of the process. FIG. 9 shows a schematic diagram of the fourth stage of the process. In FIG. 10, the schematic diagram of a back side lamination process is shown. In FIG. 11, the schematic diagram of a front and back layer unification process is shown.

  First, the front side lamination step will be described. As shown in FIG. 6, in the first stage of this step, the binding layer 200 and the water retention layer 201 are bonded by a needle punch method. Specifically, first, the binding layer 200 and the water retention layer 201 are laminated. Next, the needle 90 is pierced to interlace the fibers of each layer. In this way, the binding layer 200 and the water retention layer 201 are bonded. As shown in FIG. 7, in the second stage of this step, a large number of moss plant gametophytes 200 a are sown on the tie layer 200. As shown in FIG. 8, in the third stage of this step, first, a large number of moss plant gametophytes 200 a are covered with a protective layer 202. Next, the protective layer 202 and the bonded body of the binding layer 200 and the water retention layer 201 are bonded by the needle punch method. As shown in FIG. 9, in the fourth stage of this process, the artificial turf 203 is planted from above the protective layer 202 in a predetermined pattern by a tufting method. Thus, the front side laminated body which consists of the artificial turf 203, the protective layer 202, the moss plant game body 200a, the binding layer 200, and the water retention layer 201 is produced.

  Next, a back side lamination process is demonstrated. As shown in FIG. 10, in this step, a blocking layer 205 is formed on the back surface of the heat insulating layer 206 by a laminating method. That is, the back surface of the heat insulating layer 206 is coated with the molten blocking layer 205. Thus, the back side laminated body which consists of the heat insulation layer 206 and the interruption | blocking layer 205 is produced.

  Next, the front and back layer combining step will be described. As shown in FIG. 11, in this step, the front side laminate (artificial grass 203, protective layer 202, moss plant gametophyte 200a, binding layer 200, water retention layer 201) and the back side laminate (heat insulation layer 206, barrier layer). 205) are combined by a chemical bond method. In this way, the greening member 20 is produced.

(Greening member bonding process)
In FIG. 12, the schematic diagram of a greening member adhesion process is shown. As shown in FIG. 12, in this step, the adhesive layer 22 is disposed on the back surface of the blocking layer 205. Then, the adhesive layer 22, that is, the greening member 20 is bonded to the surface of the base material 21. Thus, the greening panel 2 is produced. In addition, the wire mesh 23 is attached in the manufacturing method of the greening wall mentioned later.

[Manufacturing method of green wall]
Next, the manufacturing method of the greening wall 1 is demonstrated. The method for manufacturing the greening wall 1 includes a mold assembly process, a molding process, and a mold disassembly process. In FIG. 13, the perspective view of the formwork used for the manufacturing method of a greening wall is shown. FIG. 14 shows a partial cross-sectional view of the same frame as viewed from the left.

(Formwork configuration)
As shown in FIGS. 13 and 14, the mold 8 includes a mold member 80, pipes 81 and 82, a washer 83, a foam tie 84, a connection plate 85, a nut 87, a panel connection body 9, and a shaft. A leg 50, a separator 51, and a regicon 52 are provided. The mold member 80 is made of plywood and has a rectangular shape. A mold release agent is applied to the front surface of the mold member 80. The panel coupling body 9 has a rectangular plate shape. The adjacent greening panels 2 of the panel connector 9 are connected by a steel connecting plate 85. The panel coupling body 9 and the mold member 80 are erected at a predetermined interval in the front-rear direction.

  The arrangement of the members shown below is symmetrical in the front-rear direction on the panel connector 9 side (front side) and the mold member 80 side (rear side). Here, only the members on the panel connector 9 side will be described.

  The plurality of pipes 81 and 82 are arranged in a lattice shape as a whole. The plurality of pipes 81 and 82 reinforce the panel connector 9 from the front. The pipe 81 is made of steel and extends in the vertical direction. The twelve pipes 81 are arranged on the front surface of the panel connector 9. The pipe 82 is made of steel and extends in the left-right direction. The 16 pipes 82 are arranged in front of the pipe 81.

  A set of the foam tie 84, the shaft foot 50, the separator 51, the regicon 52, the washer 83, and the nut 87 is arranged in the mold 8 at predetermined intervals. The separator 51 is disposed between the panel connector 9 and the mold member 80. The regicon 52 is fixed to both ends of the separator 51 in the front-rear direction. The shaft foot 50 is made of steel and has a round bar shape. The shaft leg 50 extends in the front-rear direction. The rear end of the shaft foot 50 is fixed to the regicon 52. The front end of the shaft foot 50 penetrates the greening panel 2. The washer 83 is made of steel and has a C-shaped plate shape that opens rearward. The washer 83 holds the two pipes 82 from the front. The foam tie 84 is made of steel and extends in the front-rear direction. The foam tie 84 is disposed on the front surface of the greening panel 2. A recess 840 is formed on the rear surface of the foam tie 84. A shaft portion 841 is formed at the front portion of the foam tie 84. The recessed portion 840 and the shaft portion 841 are each provided with a screw portion. The front end of the shaft leg 50 is fixed to the recess 840. The shaft portion 841 penetrates between the two pipes 82 and projects forward of the washer 83. The nut 87 is fixed to the protruding end (front end) of the shaft portion 841.

(Formwork assembly process)
In the mold assembly process, first, the panel connector 9 and the mold member 80 are arranged facing each other in the front-rear direction. Next, the 12 pipes 81 and the 16 pipes 82 are assembled to the front side of the panel connecting body 9 using the foam ties 84, the shaft legs 50, the separators 51, the register control 52, the washers 83, and the nuts 87. In addition, twelve pipes 81 and sixteen pipes 82 are assembled on the rear side of the mold member 80. In this way, the mold 8 is assembled.

(Molding process)
In the molding process, a concrete raw material, that is, a wall material 70 is poured into the mold 8. That is, the wall material 70 is poured between the rear surface of the base material 21 of each greening panel 2 and the front surface of the mold material 80. Here, the base material 21 is made of cement and is porous. For this reason, the wall material 70 penetrates well into the base material 21. When the wall material 70 is cured, the wall body 7 (see FIG. 1) is formed. And the wall main body 7 and the base material 21 of each greening panel 2 couple | bond together firmly.

(Formwork disassembly process)
In the mold disassembling step, first, the washer 83 is removed from the foam tie 84 by removing the nut 87 from the shaft portion 841. Subsequently, the pipe 81 and the pipe 82 are removed from the front side of the panel connection body 9 and the rear side of the mold member 80. Then, the foam tie 84 is removed from the shaft foot 50. Thereafter, the mold member 80 is removed from the rear shaft leg 50. Further, the rear axle 50 is removed from the rear register 52. Finally, as shown in FIGS. 2 to 4, the metal mesh 23 is attached to the front surface of the greening member 20 by attaching the clip 53 and the cap nut 54 to the left front shaft foot 50. In this way, the green wall 1 is produced.

[Function and effect]
Next, the effect of the manufacturing method of the greening member 20, the greening panel 2, and the greening wall 1 of this embodiment is demonstrated. The greening member 20 of the present embodiment includes a water retention layer 201 made of nonwoven fabric. The water retention layer 201 contains irregular cross-section fibers. The irregular cross-section fiber has a larger specific surface area than the perfect circular cross-section fiber. For this reason, water retention is high. Therefore, it is suitable for being used for a standing wall arranged substantially perpendicular to the ground. Moreover, the greening member 20 of this embodiment can ensure high water retention regardless of the cross-sectional shape of the outer surface. Therefore, the outer surface shape design and design freedom are high.

  Moreover, the protective layer 202 of the greening member 20 of this embodiment has water solubility. For this reason, the protective layer 202 dissolves with time due to rainfall or the like, and eventually disappears. Moreover, the eluate of the protective layer 202 is neutral. For this reason, there is no possibility of inhibiting the growth of the moss plant gametophyte 200a.

  Further, the greening member 20 of the present embodiment includes a large number of artificial turf 203. For this reason, even when the growth of the moss plant gametophyte 200a is slow, or when the moss plant gametophyte 200a withered, the color of the moss plant gametophyte 200a is poor. A beautiful appearance can be secured. Further, the moss plant gametophyte 200a can be protected from artificial mischief, wind, and pressure. Further, by adjusting the size, arrangement pattern, arrangement density, and the like of the artificial turf 203, the amount of sunlight irradiated to the moss plant gametophyte 200a can be adjusted.

  Further, the binding layer 200 of the greening member 20 of the present embodiment is made of a non-woven fabric that is finer than the water retention layer 201. For this reason, it is difficult for the moss plant gametophyte 200a to fall off the tie layer 200.

  Further, the binding layer 200 of the greening member 20 of the present embodiment is produced by a spunbond method. For this reason, it is hard compared with the water retention layer 201, and its shape retainability is high. Therefore, as shown in FIG. 8, even if a needle for planting artificial turf 203 enters the tie layer 200, the tie layer 200 is not easily swayed. In addition, the tie layer 200 is difficult to wrinkle. Moreover, even when the greening member 20 absorbs water, the shape at the time of drying is easily maintained.

  Further, the greening member 20 of the present embodiment includes a blocking layer 205. For this reason, as shown by the arrow Y <b> 1 in FIG. 5, it is possible to suppress the moisture of the water retention layer 201 from escaping to the base material 21. In addition, as shown by an arrow Y2 in FIG. 5, it is possible to suppress the alkaline components of the base material 21 and the wall body 7 from penetrating into the heat insulating layer 206.

  Further, the greening member 20 of the present embodiment includes a heat insulating layer 206. For this reason, the water retention layer 201 can be protected from heat generated when the barrier layer 205 in the molten state is laminated on the heat insulating layer 206.

  Moreover, the heat insulation layer 206 has not only a heat insulation ability but also a water retention ability. The water retention layer 201 mainly secures moisture necessary for the growth of the moss plant gametophyte 200a. However, the water retention layer 201 is close to the moss plant gametophyte 200a. For this reason, when the water retention capacity of the water retention layer 201 is excessively increased, the water content becomes excessive, and the moss plant gametophyte 200a may become ill.

  In this regard, according to the greening member 20 of the present embodiment, the heat insulating layer 206 has water retention capability. For this reason, compared with the case where the water | moisture content required for the growth of the moss plant gametophyte 200a is ensured only with the water retention layer 201, the amount of water retention can be increased. Therefore, for example, even in a place where there is little rainfall, the moss plant gametophyte 200a is likely to grow without being in a tentative state (dormant state).

  Further, the heat insulating layer 206 is separated from the moss plant gametophyte 200a as compared with the water retention layer 201. For this reason, the temporary root of the moss plant gametophyte 200 a is unlikely to reach the heat insulating layer 206. Therefore, it is difficult for the moss plant gametophyte 200a to be soaked in the moisture of the heat insulating layer 206. Therefore, the moss plant gametophyte 200a is unlikely to be ill. On the other hand, when the moisture of the water retaining layer 201 is insufficient, the moisture of the heat insulating layer 206 moves to the water retaining layer 201. For this reason, the water | moisture content of the water retention layer 201 can be replenished. Thus, the heat insulation layer 206 has a backup function of the water retention layer 201.

  Further, the adhesive layer 22 of the greening panel 2 of the present embodiment is attached to the blocking layer 205. For this reason, compared with the case where the adhesion layer 22 is affixed on the water retention layer 201 and the heat insulation layer 206 made from a nonwoven fabric, the adhesion layer 22 is hard to peel.

  Moreover, according to the greening panel 2 of this embodiment, the greening member 20 is attached to the base material 21 via the adhesion layer 22. For this reason, for example, when the moss plant gametophyte 200a of the greening member 20 is withered or when the greening member 20 is damaged, the greening member 20 can be easily replaced. Therefore, the greening panel 2 of this embodiment is excellent in maintainability.

  Moreover, according to the greening panel 2 of this embodiment, the 15 greening members 20 are arrange | positioned with respect to the single wall main body 7. FIG. For this reason, the beauty of the entire greening wall 1 can be maintained by replacing only the desired greening member 20. Also in this point, the greening panel 2 of this embodiment is excellent in maintainability.

  Moreover, according to the manufacturing method of the greening wall 1 of this embodiment, attachment of the greening panel 2 with respect to the wall main body 7 and shaping | molding of the wall main body 7 can be performed in a shaping | molding process in parallel. For this reason, compared with the case where the greening panel 2 is attached to the existing wall main body 7 by retrofitting, the degree of freedom of the attachment location (for example, a high place) is increased.

  Moreover, when attaching the greening panel 2 with respect to the existing wall main body 7, it is necessary to form a scaffold at least twice at the time of construction of the wall main body 7 and at the time of construction of the greening panel 2. On the other hand, according to the manufacturing method of the greening wall 1 of this embodiment, the frequency | count of assembling a scaffold only needs one time. For this reason, attachment cost can be reduced. Further, a blocking layer 205 is interposed between the wall material 70 and the heat insulating layer 206. For this reason, it can suppress that the wall material 70 osmose | permeates the heat insulation layer 206. FIG.

  Moreover, according to the manufacturing method of the greening wall 1 of this embodiment, the wall main body 7 is a product made from concrete. The base material 21 is made of cement. That is, the base material 21 is porous. For this reason, the wall material 70 permeates the base material 21 well in the molding step. Therefore, the bondability between the wall body 7 and the base material 21 is improved.

  Moreover, according to the manufacturing method of the greening wall 1 of this embodiment, the panel coupling body 9 and the mold member 80 are reinforced by the pipes 81 and 82 in the molding step. For this reason, the panel connector 9 and the mold member 80 are not easily deformed by the injection pressure of the wall member 70.

  Moreover, according to the manufacturing method of the greening wall 1 of the present embodiment, the wire net 23 is attached using the used regicon 52 in the mold disassembling process. That is, the regicon 52 originally used for securing the space between the panel connector 9 and the mold member 80 can be reused for attaching the wire mesh 23. For this reason, compared with the case where the parts for attaching the metal mesh 23 are separately arranged, the number of parts is reduced. Further, unlike the rear register 52 shown in FIG. 4, it is not necessary to seal the recess with a filler.

  Moreover, according to the manufacturing method of the greening wall 1 of this embodiment, the mold release agent is applied to the front surface of the mold member 80, while the mold release agent is not applied to the rear surface of the base material 21. That is, a release agent is selectively applied. For this reason, the mold material 80 tends to be separated from the wall body 7 in the mold disassembling process. On the other hand, the base material 21 and the wall body 7 are firmly joined.

<Second embodiment>
The difference between the present embodiment and the first embodiment is that a groove is disposed on the surface of the greening member 20. Here, only differences will be described. In FIG. 15, sectional drawing seen from the left of the greening wall of this embodiment is shown. In addition, about the site | part corresponding to FIG. 4, it shows with the same code | symbol. FIG. 16 shows an enlarged view in a circle XVI in FIG.

  As shown in FIGS. 15 and 16, a groove 204 is disposed in the protective layer 202 and the binding layer 200. The groove portion 204 extends in the left-right direction. A total of five grooves 204 are arranged at predetermined intervals in the vertical direction. The cross-sectional shape of the groove part 204 has a square shape. The groove portion 204 is formed by welder processing.

  As shown in FIG. 17, a recess 71 is formed on the rear surface of the wall body 7. The rear end of the separator 51 protrudes from the bottom surface of the recess 71. The recess 71 is an arrangement trace of the P-con 89 when the greening wall 1 is manufactured. The shaft portion 890 of the P-con 89 is fixed to the rear form tie 84 in FIG.

  The manufacturing method of the greening member 20, the greening panel 2, and the greening wall 1 of this embodiment is the same as the manufacturing method of the greening member, the greening panel, and the greening wall of the first embodiment with respect to the parts having the same configuration. Has a working effect. Moreover, according to the greening member 20 of this embodiment, the flow of the water which flows down through the greening member 20 at the time of raining etc. can be interrupted | blocked. For this reason, it becomes possible to suppress the dispersion | variation in the water retention of the whole greening member 20 by the water suction capability which the water retention layer 201 has, and water retention becomes still higher. Moreover, according to the greening member 20 of this embodiment, the groove part 204 of a desired shape can be easily formed by a welder process. Moreover, the recessed part 71 may be formed in the rear surface of the wall main body 7 like the greening wall 1 of this embodiment. That is, the rear register 52 (see FIG. 4) may not be arranged.

<Others>
As mentioned above, embodiment of the manufacturing method of the greening member of this invention, the greening panel, and the greening wall was described. However, the embodiment is not particularly limited to the above embodiment. Various modifications and improvements that can be made by those skilled in the art are also possible.

  In the said embodiment, although the metal mesh 23 was arrange | positioned in the greening panel 2, the metal mesh 23 does not need to be arrange | positioned. Further, the material of the wire mesh 23 is not particularly limited. It may be made of metal or resin. Further, the mesh size of the wire mesh 23 is not particularly limited. As shown in FIG. 3, it is sufficient that the clip 53 can be fixed to the front surface of the greening member 20. Further, it is only necessary that the artificial turf 203 and the moss plant gametophyte 200a can protrude from the mesh.

  Moreover, the formation method of the fleece of the binding layer 200, the water retention layer 201, and the heat insulation layer 206 made of nonwoven fabric is not particularly limited. A dry method such as a carding method or an airlaid method, a wet method, a spun bond method, a melt blow method, or the like can be used.

  Moreover, the joining method of the binder layer 200, the water retention layer 201, and the heat insulation layer 206 in the nonwoven fabric joining process (refer FIG. 6) of a greening member manufacturing process is not specifically limited. In addition to the needle punch method, a thermal bond method, a chemical bond method, a spunlace method, a stitch bond method, a steam jet method, or the like can be used.

  Further, the number, shape, and size of the greening panel 2 arranged on the greening wall 1 are not particularly limited. Moreover, you may arrange | position the greening wall 1, the greening panel 2, and the greening member 20 upward. For example, the greening wall 1, the greening panel 2, and the greening member 20 may be used for rooftop greening or the like. Moreover, the arrangement number of the greening panels 2 with respect to the single wall main body 7 is not specifically limited.

  Moreover, the kind of moss plant gametophyte 200a arrange | positioned in the bonding layer 200 is not specifically limited. For example, moss plant gametophyte 200a belonging to mosses such as snago, high moss, sphagnum, sphagnum, moss such as moss, hornwort, and horns such as hornwort can be used.

  Moreover, you may adjust the magnitude | size, arrangement | positioning pattern, arrangement | positioning density, etc. of the artificial turf 203 according to the kind of moss plant gametophyte 200a. Moreover, you may adjust content of the irregular cross-section fiber of the water retention layer 201 according to the kind of moss plant gametophyte 200a. Moreover, you may adjust the layer thickness of each layer according to the kind of moss plant gametophyte 200a.

  Moreover, the kind of irregular cross-section fiber of the water retention layer 201 is not particularly limited. Preferably, the larger specific surface area is better. The fiber thickness should be thin. From these viewpoints, special fibers such as Y-shaped cross-section fibers and heat splitting fibers are suitable.

  Moreover, the kind of fiber which comprises the binder layer 200 and the heat insulation layer 206 is not specifically limited. For example, general-purpose polyester fibers or recycled PET fibers are suitable. Further, the thickness, length, and basis weight of the fiber are not particularly limited. Moreover, the adhesive layer 200 may be an adhesive nonwoven fabric. In this way, the moss plant gametophyte 200a tends to stick to the tie layer 200.

  Further, the material of the protective layer 202 is not particularly limited. What is necessary is just to change the material of the protective layer 202 according to the kind of moss plant gametophyte 200a. Moreover, the protective layer 202 should just have at least one among water-soluble components, such as polyvinyl alcohol, biodegradable polyester, starch, and water-insoluble components, such as polyester, polyethylene, a polypropylene.

  When the protective layer 202 has a water-soluble component, the dissolution time of the water-soluble component can be adjusted by the material, the surface density, and the like. For example, if the dissolution time is adjusted so that the water-soluble component dissolves at an early stage of use of the greening member 20, the moss plant gametophyte 200a can be prevented from falling off during the manufacturing process and the transporting process of the greening member 20. Further, it is possible to suppress the moss plant gametophyte 200a from being damaged from the outside during the manufacturing process and the transporting process of the greening member 20.

  In addition, if the dissolution time is adjusted so that the water-soluble component dissolves according to the time when the temporary root of the moss plant gametophyte 200a takes root in the binding layer 200, the rooting of the temporary root of the moss plant gametophyte 200a is promoted. Can do. In addition, the protective layer 202 can be easily removed after the temporary root of the moss plant gametophyte 200a has taken root in the binding layer 200.

  In addition, when the protective layer 202 has a water-insoluble component, the water-insoluble portion remains even after the temporary root of the moss plant gametophyte 200a is rooted in the binding layer 200. For this reason, when the temporary root of the moss plant gametophyte 200a is entangled with the water-insoluble portion, the moss plant gametophyte 200a and the moss can be prevented from falling off the greening member 20.

  Further, the material of the blocking layer 205 is not particularly limited. Higher barrier properties against moisture and alkali components are preferred. For example, polyethylene, polypropylene, etc. are suitable. In the case where the blocking layer 205 is disposed by an adhesive, the blocking layer 205 may be bonded to the water retention layer 201 because heat is not applied to the water retention layer 201 as in the lamination method. In this way, the heat insulating layer 206 becomes unnecessary.

  Moreover, the material of the base material 21 is not specifically limited. When integration with the wall body 7 is not required, a material that does not adversely affect the moss plant gametophyte 200a, such as an alkali component, is preferable. For example, a veneer board, a foamed polyethylene board, a ceramic board (clay board etc.), etc. are suitable.

  Moreover, the material of the adhesion layer 22 is not specifically limited. The adhesive layer 22 may be formed by applying an adhesive to at least one of the back surface of the blocking layer 205 and the surface of the substrate 21.

  Moreover, the arrangement number of the groove part 204 in 2nd embodiment is not specifically limited. The greater the number of arrangements, the higher the water retention. Moreover, the extending direction of the groove part 204 is not specifically limited. The closer to the horizontal direction, the higher the water retention. Further, the depth of the groove portion 204 (length in the front-rear direction of the groove portion 204 in FIG. 16) and the groove width (length in the vertical direction of the groove portion 204 in FIG. 16) are not particularly limited. Moreover, the cross-sectional shape of the groove part 204 is not specifically limited. It may be rectangular, C-shaped, U-shaped, V-shaped, or the like.

  The material of the artificial turf 203 is not particularly limited. The surface of the artificial turf 203 may be subjected to a hydrophilic treatment. If it carries out like this, the wettability of the artificial turf 203 will improve and a water retention rate will improve. For this reason, the growth of the moss plant gametophyte 200a and moss can be promoted. The method of hydrophilic treatment is not particularly limited. For example, a treatment method such as applying a hydrophilic coating agent by a spray coating method, a dip method, a roll coating method, or the like, and drying can be used.

  Moreover, when conveying the greening member 20 and the greening panel 2, the front surface of the greening member 20 may be covered with a protective member made of cardboard or the like. If it carries out like this, the front surface of the greening member 20 can be protected from the vibration at the time of conveyance, interference with an adjacent conveyance thing, etc.

  Further, a plate material may be arranged instead of the pipes 81 and 82 shown in FIG. Even in this case, the panel connector 9 and the mold member 80 can be reinforced by the injection pressure of the wall member 70 in the molding process.

  Further, instead of the regicon 52, a coupling tool that can be attached to the separator 51 and can be attached to and detached from the shaft foot 50, such as a metal-plated long nut or a stainless steel long nut, may be used. Moreover, the coupling tool which has a recessed part by which the thread part was formed in the inner peripheral surface can be used for both axial direction surfaces. Moreover, the coupling tool which has the through-hole by which the thread part was formed in the internal peripheral surface of the axial direction vicinity at least can be used.

  As shown in FIG. 4, the connector is embedded in the wall body 7 and used for fixing the wire mesh 23. For this reason, the connection tool must be in a shape that does not turn around (the connection tool rotates together with the separator 51 and the shaft foot 50) due to the attachment / detachment and rotation of the separator 51 and the shaft foot 50. Further, the coupler is embedded in the concrete wall body 7 for a long period of time. For this reason, it is desirable that the coupling tool is made of a material that is unlikely to rust and corrodes.

  Hereinafter, a water retention experiment performed on the water retention layer 201 alone will be described.

[sample]
First, samples used in the experiment will be described. Table 1 shows a recipe for the sample.

  In Example 1-1, a Y-shaped cross-section fiber having a thickness of 4.4 dt (decitex) is included in an amount of 20% by mass, where the mass of the entire water retaining layer 201 is 100% by mass. Example 1-2 contains 20% by mass of a heat splitting fiber having a thickness of 2.2 dt. Comparative Example 1-1 is composed of general-purpose polyester fibers each having a different thickness. In Comparative Example 1-2, flame retardant fibers having different thicknesses are included.

  The fiber composition index of an arbitrary sample is a sum of numerical values obtained by multiplying the thickness of the fiber contained in the sample and the content of the fiber. For example, in the case of Example 1-1, a value obtained by multiplying the thickness of the recycled fiber manufactured by Yamaichi Co., Ltd. by 14 dt and the content of the fiber of 25% by mass, and the thickness of the general-purpose polyester fiber manufactured by Toray Industries, Inc. is 6.6 dt. And the value obtained by multiplying the content of the fiber by 35% by mass, the value obtained by multiplying the binder thickness 4.4 dt made by Unitika and the content of the fiber by 20% by mass, and the Y-shaped cross section made by Takayasu. It is the sum of the value obtained by multiplying the fiber thickness of 4.4 dt by the fiber content of 20% by mass.

[experimental method]
The experiment was performed by the following method. First, the sample is immersed in water for 5 minutes. Next, the water-absorbed sample is suspended in a vertical state. After 1 minute, the sample is leveled and the mass is measured. This mass is defined as a mass with an elapsed time of 0 hours. Then again suspend the sample vertically. Then, the sample is placed in a horizontal state at every predetermined sampling time, and the mass is measured. The water retention is calculated from the following equation, where the measured mass is M1 and the dry mass M0 of the sample.
Water retention rate (%) = ((M1-M0) / M0) × 100

[Experimental result]
The experimental results are shown in Table 2 and FIG. The water retention rate is an average value.

  From Table 2 and FIG. 18, it was found that the water retention rate at each sampling time was higher in the example than in the comparative example. Moreover, when Example 1-1 and Example 1-2 are compared, each direction of Example 1-2 containing a heat | fever division | segmentation fiber is different from Example 1-1 containing a Y-shaped cross-section fiber. It was found that the water retention rate per hour was high.

  Moreover, the water retention after 24 hours of Example 1-1 of the fiber composition index 757 (Table 1) is 145%. The water retention after 24 hours of Example 1-2 of the fiber composition index 713 (Table 1) is 250%. The water retention after 24 hours of Comparative Example 1-1 of the fiber composition index 1168 (Table 1) is 24%. The water retention after 24 hours of Comparative Example 1-2 of the fiber composition index 1903 (Table 1) is 4%. From this, it was found that the smaller the fiber composition index, the higher the water retention rate.

  In addition, the water retention after 24 hours should be 100% or more and 200% or less. The reason is that when the water retention rate is less than 100%, moss plant gametophyte and moss growth are likely to be inhibited. Further, when the water retention rate exceeds 200%, root rot is likely to occur.

  Hereinafter, the water retention experiment performed on the greening member 20 will be described with reference to FIG.

[sample]
First, samples used in the experiment will be described. Table 3 shows a sample composition table.

  The sample dimensions are 600 mm long x 600 mm wide. As shown in FIG. 5, Example 2-1 includes a binding layer 200, a water retention layer 201, a protection layer 202, a large number of artificial turf 203, a blocking layer 205, and a heat insulating layer 206. Yes. In the tie layer 200, a moss plant gametophyte 200a is disposed.

  As shown in Table 3, the water retention layer 201 of Example 2-1 contains 20% by mass of heat splitting fibers having a thickness of 2.2 dt, where the mass of the entire water retention layer 201 is 100% by mass. Similarly, the heat insulating layer 206 contains 20 mass% of heat splitting fibers having a thickness of 2.2 dt, where the mass of the entire heat insulating layer 206 is 100 mass%. The barrier layer 205 is made of PE.

  Comparative Example 2-1 includes a tie layer 200, a water retention layer 201, and a large number of artificial turf 203. In the tie layer 200, a moss plant gametophyte 200a is disposed. The water retention layer of Comparative Example 2-1 is composed of general-purpose polyester fibers each having a different thickness.

[experimental method]
The experiment method is the same as the water retention experiment (Example 1) performed on the water retention layer 201 alone. For this reason, explanation is omitted.

[Experimental result]
The experimental results are shown in Table 4 and FIG.

  From Table 4 and FIG. 19, it was found that the water retention rate at each sampling time was higher in the example than in the comparative example. In addition, the water retention after 72 hours should be 50% or more. The reason is that when the water retention rate is less than 50%, moss plant gametophyte and moss growth are likely to be inhibited.

  Hereinafter, a water retention experiment performed on the greening member 20 having the groove portion 204 will be described with reference to FIGS. 15 and 16.

[sample]
First, samples used in the experiment will be described. Table 5 shows the dimensions of the groove portions of each sample and the moldability during the welding process.

  Example 3-1 is the same sample as Example 2-1. That is, the groove part 204 is not arrange | positioned in Example 3-1. Examples 3-2 to 3-5 are samples in which the grooves 204 are formed by welder processing as compared to Example 3-1. The moldability of the groove part 204 in Examples 3-2 to 3-5 was good. The interval between adjacent grooves 204 is 10 cm.

[experimental method]
The experiment method is the same as the water retention experiment (Example 1) performed on the water retention layer 201 alone. For this reason, explanation is omitted.

[Experimental result]
The experimental results are shown in Table 6 and FIG.

  From Table 6 and FIG. 20, it was found that Examples 3-2, 3-4, and 3-5 had a higher water retention rate at the beginning of the experiment (at 0 hour) than Example 3-1. Moreover, it turned out that the water retention after 72 hours is higher in Examples 3-2, 3-4, and 3-5 than in Example 3-1. Moreover, it turned out that the water retention rate for each sampling time is higher in Examples 3-4 and 3-5 than in Example 3-1. In addition, the water retention after 72 hours should be 80% or more. The reason is that when the water retention rate is less than 80%, moss plant gametophyte and moss growth are likely to be inhibited.

  Further, the interval between adjacent groove portions 204 is preferably 5 cm or more and 20 cm or less. The reason is that when it is less than 5 cm, the water retention becomes excessively high and root rot easily occurs. Moreover, when it exceeds 20 cm, it is because the sufficient water retention improvement effect by groove | channel part 204 arrangement | positioning is difficult to be acquired.
